Hagibis LED Display USB C Adapter 240W 40Gbps 8K@60Hz, USB4 Connecter for Thunderbolt 4/3, iPhone 16 15 Pro Max, Current Voltage Fast Charging Monitoring Display Tester Detector (TUA04)

Independent review. These are the best I know of and have personally tested across devices. USB4 support is crucial key. Works with new and old. I have bought these 3 times. No failures but needed more. Caution- they are really small. Easy to lose. Keep spares in the included zip lock pouch.

I recently tried the LED Display USB-C Adapter and was impressed by its support for Thunderbolt 4/USB 4.0 speeds. Unlike similar products, this one is particularly special! Instead of USB 2.0 500Mbps speeds, it handles data transfers up to 40Gbps meaning it can deliver a crisp 8K@60Hz output, making it perfect for high-resolution displays while showing power reportings.Build Quality & Connector DurabilityThe USB-C connector is significantly more durable than other brands I've tested. It holds up well even after frequent use, showing no signs of wear, especially on the USB C male connector piece which is typically the first breaking point of any USB connector. This sturdiness is a major plus if you often connect and disconnect devices.LED Display FunctionThe adapter features an LED display that cycles through Volts (V), Amps (A), and Wattage (W) every 5 seconds. While this offers useful insights, the cycling can be slightly distracting and overwhelming, and there's some LED bleed that makes it hard to read at certain angles. However, the readings are impressively accurate compared to similar adapters.Performance & Heat ManagementThis adapter can apparently handle up to 240W of power. However, as of 2024 to my knowledge no charging device offered to the public as a standard is able to reach such a high rating. What I have tested is charging my Meta Quest 2. At higher amperage, it gets warm but never uncomfortably hot like others have stated. Interestingly, it stays cool even with higher voltage, indicating excellent heat management.Pros:- Supports Thunderbolt 4 / USB 4.0 speeds up to 40Gbps- High power capacity (240W) with decent heat management- Durable USB-C connector, more robust than many other brands (I haven't seen any reviews from others on this item being damaged either)- Accurate power reporting for volts, amps, and wattage- Reporting goes down to decimal values, 1/10 or 0.1, rather than whole numbers, 1, 2, 3, 4...Cons:- LED display cycles every 5 seconds while updating 5 ticks of the V / A / W values, which can be slightly distracting (it shows the voltage for 5 times in 5 seconds, next the amperage for 5 times in 5 seconds, then the amperage for 5 times in 5 seconds, then recycles again)- Minor LED light bleed between readings (makes it a bit difficult to read double digit values)

This works well, and even helped me identify an oddly behaving USBc charger that was dipping in wattage and causing my laptop to warn of low charge.I wish I could select the displayed value, you just have to wait for it to cycle between values, and I'm impatient.I like this enough that I'm buying two more.This works with my docking station. I tried a different brand that would not work with my docking station, but this one works well. This also has a display that is right side up. Both my work and home laptop have the charger on the left, many other brands display upside down for me.

So this device works as intended. When you plug in a cable, it will output the wattage, volts, and amps in that order. it automatically cycles through the information. I can safely say that it works for any device below 100w. However past 100w, I cannot say that I would trust this device. I currently do not have a device that can pull more than 100w, but of the two devices that pull 100w, my power bank and gaming laptop, I would trust neither. This device gets unreasonably hot during use with both of these devices. not only that, the power doesn't seem to get past 95w when the device is plugged in. When the cable is plugged in without the meter, it works fine and the cable just gets warm. But I would imagine that someone could eventually burn their hands on this device if they would be holding onto the cable for a ~5 minute duration. Excess heat in this capacity does not give me the confidence that it will support 240w of continuous draw. even 100w seems to be the realistic limit. Since a device that uses 180w or 240w over USB C doesn't exist at the time of this review. I would say that for right now, I would say the realistic limit of 100w to 140w is possible, but I would not be the first to test it.

The power meter works well. Be aware that it cycles between Volts, Watts, and Amps; there is no way to select which value to display or the orientation.I only tested it up to 80 watts; it didn't get hot. But I didn't test up to the full 240 watt rating

Digital monitor displays charging rates.Easily moved from one to another device.

Handy little add on to see how much power is going into/out of items. Fits the cables I've used tightly and also helps to know that you're getting juice into something that doesn't have any charge indicators on it.

misleading photos , all photos show 2 , it came with 1 , kind of mad about it , and returned it .
